| 摘要: |
| 基于预测函数设计了励磁控制器对发电机端电压进行控制。同时设计一种以发电机功角偏差、角速度偏差以及有功功率偏差的线性组合作为控制目标的线性多变量励磁控制器。将2种励磁控制器进行结合，以实现预测函数和线性多变量并行励磁控制，在有效提高电力系统稳定性的前提下还能解决发电机端电压的稳定问题。最后通过MATLAB／Simulink仿真证明了改进后的励磁控制器的有效性。 |

| Abstract: |
| An excitation controller based on predictive function is designed to control the terminal voltage of generator. A linear multi-variable excitation controller is designed as well，which takes the linear combination of the generator power angle deviation，angular velocity deviation and active power deviation as its control target. Two excitation controllers are integrated to realize the parallel excitation control based on the predictive function control and the linear multi-variable control，which ensures the terminal voltage stability of generator while improves the stability of power system effectively. The effectiveness of the integrated controller is proved by the simulative results of MATLAB／Simulink. |
